It was found that oxidation potentials of methanes with π-electron substituents were decreased by introduction of a trimethylsilyl group. The anodicoxidation of benzyl-, allyl-, aryl(or alkyl)thiomethyl-, and aryloxymethyl-substituted trimethylsilanes smoothly proceeded in the presence of nucleophiles, e.g. alcohols and carboxylic acids, to eliminate the trimethylsilyl groups giving the corresponding

Oxalic acid catalyzes a reaction between dithioacetals and acetals. This reaction is useful in a new and eco-friendly method to convert dithioacetals to carbonyl compounds.
5,5-tetramethyl-2-phenylsulfanylmethyl-[1,3,2]dioxaborolane and tetra-n-butylammonium phenylthiomethyltrifluoroborate were comparatively studied by cyclic voltammetry measurements and we found for the first time the β-effect of organoborate, which was indicated by experimental and theoretical aspects. The organoborate was found to have a much lower oxidation potential compared to the organoborane.
